Hmmm let's take another stab, found some problems oops...
Fixed them unless something blew, right now I get 465v over R30, -260-270v over R7 and -80v on the grid with GZ34 plugged in.
No voltage over pin 4 on the output sockets.
Plugged in the 5842's and R27 blew spectacularly...

Here we go again... Okay replaced the Q's or mosfets, and the resistor that blew, from the tubelab checkout page:

"Put a meter from the grid of the output tubes to ground. One meter for each tube. Power up the board. Each meter should read a negative voltage. With ONE HAND BEHIND YOUR BACK carefully adjust one of the bias pots (R12 or R23). The negative voltage for the corresponding output tube should change. Set it to the most negative voltage, and then adjust the bias pot for the other channel."

From what I read on there I adjusted them to the most negative they would go, they went all the way to -140 and -152, is this OK?

Never mind I see some of you guys use these tubes, any ideas why there is no voltage, there is around -110v to -125v on the other side of the caps. On startup the plate reads negative then as B+ starts to turn positive the plate just goes to 0.
